League of Legends Spell Vamp

What Does Spell Vamp Do?

Spell Vamp grants the attacker a percentage of their damage, dealt via spells/abilities, back as health. This only applies to skills that do not apply on hit effects (such as Kennen's Thundering Shuriken and Brand's Sear).

It is important to note that Spell Vamp will only do 33% of however much you have Spell Vamp you have if you use an AoE spell. As an example, if Lee Sin uses his Tempest a third of the normal effectiveness of his spellvamp from Iron Will. This is in place to stop champions from healing high amounts of health from minion waves. However, if a spell has some form of multi/single target effect change (such as Mace of Spades) it will only heal 33% if you hit more than one. Spells such as Ahri's Fox-Fire which just count as multiple instances of single target spells (as they only hit one each) will apply the full 100% of your spell vamp.

Spell Vamp is reduced by healing reduction effects such as Ignite.
